Abstract

The invention discloses an endoscope operation suture line with a lock, and relates to a suture line used when tissues are sutured in an endoscope operation. The endoscope operation suture line is mainly designed for solving the problem that when the endoscope operation is carried out, the two tissues cannot be tied tightly through an existing suture line. The endoscope operation suture line comprises a suture line body; a suture needle is arranged at one end of the suture line body; the other end of the suture line body is connected with the lock; a core cavity is contained in the lock; an opening is formed in the top of the core cavity; corresponding line locking holes are formed in the front wall and the back wall of the lower portion of the core cavity; a lock cylinder is installed in the core cavity; the upper portion of the core cavity is narrower than the lower portion of the core cavity; the corresponding lock cylinder is narrow in top and wide in bottom; an elastic clamping pin is arranged on the inner wall of the upper portion of the core cavity; and an elastic clamping pin matched with the elastic clamping pin on the core cavity is arranged at the upper portion of the lock cylinder. A transverse flange is arranged at the cavity bottom of the core cavity; the bottom edge of the lock cylinder is correspondingly provided with a groove matched with the flange. A protrusion is arranged at the bottom of the lock and comprises an iron block; and the interior of the top end of the lock cylinder is wrapped by the iron block. The endoscope operation suture line has the beneficial effect that the suture line is rapid and convenient to lock.

Description

A kind of locking endoscope-assistant surgery suture

Technical field:

The present invention relates to one kind is in endoscope-assistant surgery, to the suture being used when organizing and suturing.

Background technology:

At present when endoscope-assistant surgery sutures to tissue, routine is that absorbable suture is beaten surgery after it has been gathered Knot, surgeons' knot is that two steps break into, problem be when the two pieces of tissue distance being sutured farther out when, carry out the after completing the first step again During two steps, drawn by two pieces of tissues and stretched, two tensioned for first step the end of a thread can be stretched pine, so that two pieces of tissue distance is widened, Thus being difficult to fasten two pieces of tissues on request.

Content of the invention:

The technical problem to be solved is to provide one kind after endoscope-assistant surgery sutures to tissue, and two are stitched Zygonema head is easy to the locking endoscope-assistant surgery suture locked.

Above-mentioned purpose is achieved in that it includes suture, and there are sewing needle, the other end of suture in one end of suture It is connected with lock body, in lock body, has core cavity, opening is arranged at the top of core cavity, the front and back walls of core cavity bottom have mutually corresponding Locking wire hole, the lowest part in locking wire hole is slightly above core cavity bottom of chamber or with core cavity bottom of chamber in same level, core cavity built with lock core, Skid off from the opening at core cavity top for anti-lock core, the top of core cavity is narrower than bottom, corresponding lock core is also up-narrow and down-wide, lock core with Gap is suitably left, core cavity upper inside wall is provided with elastic bayonet lock one, lock core top is provided with and the elasticity in core cavity between core cavity The elastic bayonet lock two that bayonet lock one matches, the elastic bayonet lock one in core cavity (refers to vertical with the thickness of the elastic bayonet lock two on lock core Thickness on direction or claim height) equal length of sum and locking wire bore dia；Elastic bayonet lock on lock core in core cavity at ordinary times The top of two elastic bayonet locks one being placed in core cavity, the upper end of lock core is exposed from the opening at core cavity top.

When the lowest part in locking wire hole is slightly above core cavity bottom of chamber, then the elastic bayonet lock in core cavity and the elastic bayonet lock on lock core Thickness sum is also more bigger than the length of locking wire bore dia, so that after suture penetrates locking wire hole, lock core is pressed downward suture, lock When in the elastic card pin card of core and core cavity, suture can be compressed by lock core, anti-sliding stop.

Horizontal fin can be set on core cavity bottom of chamber, the corresponding bottom edge in lock core sets and described fin phase The groove joined.

A projection can be set in the bottom of lock body, be surrounded by iron block in projection, and also wrap up iron block in the top of lock core.And Make Special surgical pincers, described Special surgical clamps jaw upper and lower band recess, is equipped with strong magnet in upper and lower recess, with operation Clamp exposes in lock core on the end of lock body core cavity opening and the projection of lock body bottom, smoothly picks up lock to reach in pneumoperitoneum chamber Body, lock body can flexible rotating, have good operation compliance, be easy to for lock body to be snapped down to suitable location close to interpolation slit in locking wire hole Pin.

Using method and advantage: after endoscope-assistant surgery will be good for tissue apposition, with sewing needle, suture is penetrated the lock of lock body Lock core is depressed after tension by string holes with operating forceps, so that lock core bottom edge suture is pressed on core cavity bottom of chamber, now, on lock core The elastic bayonet lock in portion is just stuck in below core cavity elastic bayonet lock, and suture is locked.Advantage is convenient fast during suture locking Victory, can shorten suture time, significantly lower operation easier during traditional endoscope-assistant surgery knotting and operating time, when reduction patient is long Between anesthetic risks and intraoperative hemorrhage, improve patient's operating efficiency.

Brief description:

Fig. 1 is the structural representation of the present invention；

Fig. 2 is the partial enlargement side-looking knot setting fin and setting groove part on the edge of lock core bottom in core cavity bottom of chamber in the present invention Structure schematic diagram.

Specific embodiment:

With reference to Fig. 1,2, it includes suture 1, and there is sewing needle 2 one end of suture, and the other end of suture is connected with lock Body 3, has core cavity 4 in lock body, opening is arranged at the top of core cavity, has mutually corresponding locking wire hole in the front and back walls of core cavity bottom 5, the lowest part in locking wire hole is slightly above core cavity bottom of chamber or with core cavity bottom of chamber in same level, and core cavity, built with lock core 6, is anti- The opening from core cavity top for the lock core skids off, and the top of core cavity is narrower than bottom, and corresponding lock core is also up-narrow and down-wide, lock core and core cavity Between suitably leave gap, core cavity upper inside wall is provided with elastic bayonet lock 1, and lock core top is provided with and the elastic bayonet lock in core cavity The elastic bayonet lock two that one matches, the thickness of the elastic bayonet lock two on elastic bayonet lock one and lock core in core cavity (refers to vertical direction On thickness or claim height) equal length of sum and locking wire bore dia；Elastic bayonet lock two on lock core is placed in core cavity at ordinary times Elastic bayonet lock one top, the upper end of lock core is exposed from the opening at core cavity top.

Horizontal fin 8 can be set on core cavity bottom of chamber, the corresponding bottom edge in lock core sets and described fin phase The groove 9 of coupling.

A projection 10 can be set in the bottom of lock body, be surrounded by iron block 11 in projection, and also wrap up iron in the top of lock core Block.And making Special surgical pincers, described Special surgical clamps jaw upper and lower band recess, is equipped with strong magnet in upper and lower recess, uses Operating forceps is clipped in lock core and exposes on the end of lock body core cavity opening and the projection of lock body bottom, is smoothly picked up in pneumoperitoneum chamber with reaching Rise lock body, lock body can flexible rotating, have good operation compliance, be easy to by lock body be snapped down to suitable location in locking wire hole insert Sewing needle.
